Abstract

The invention discloses a structure and method for reducing the equivalent unsprung weight of a wheel electrically-driven system of a single trailing arm type suspension, which is characterized in that an elastic rubber hinge is supported on a frame, one end of a swing arm of the single trailing arm type suspension is connected with the elastic rubber hinge, and the other end of the swing arm is connected with a reducer casing; the reducer casing is connected with a sleeve of a half axle; a motor is fixedly arranged on the reducer casing, the power output end of the motor is connected with a small gear, then the small gear is meshed with the large gear, and the large gear is connected with the sleeve of the half axle; and after the gear reducing is performed, the power is outputted to a rim by the half axle so as to drive wheels. The equivalent unsprung weight is reduced by reducing the distance between the mass centre of non-concentric parts of a wheel and a central swing axis of the single trailing arm type suspension. The structure and method disclosed by the invention have the advantages of increasing the vibration frequencies of wheels, reducing the resonance, reducing the impact and vibration from road surfaces, and improving the running smoothness of vehicles.

Description

technical field [0001] The invention relates to the field of electric vehicle chassis and transmission, in particular to a structure and method for reducing the equivalent unsprung mass of a single trailing arm suspension wheel side electric drive system. Background technique [0002] The size of the car's unsprung mass (unsprung mass) affects the driving safety and comfort of the car. At present, the wheel-side electric drive system represented by electric wheels has become a research hotspot due to its simple drive system and vehicle structure, high transmission efficiency, and independent control of the torque of each drive wheel, which is conducive to improving driving performance under harsh road conditions. . But because the motor is installed in the drive wheel, the unsprung mass of the car will be increased. [0003] In the past, when calculating the unsprung mass of a car, the mass of all parts in the wheel was directly regarded as the unsprung mass. But in f...
